I'm confused, the answers are larger than the trail?
Answer:
7.7 x 10²?
Step-by-step explanation:
24 +13 + 16 +3 = 56
so if the total was 56 and the cashier gave her 4$ of change back then she gave 60$ in total
60 - 56 = 4
she gave 60$ in total
Answer:
(x, y) = (1, 4)
Step-by-step explanation:
Given: x+y=5 and 2x-y=-2
Solve for y and x
x+y=5; solve for y
y = 5 - x; substitute into other equation
2x-y= -2
2x - (5 - x) = -2
2x - 5 + x = -2; combine x's
3x - 5 = -2; add 5 to both sides
3x =3; divide by 3
x = 1; use this to solve for y
x+y=5
1 + y = 5; subtract 1 from both sides
y = 4
(x, y) = (1, 4)
